Answer:
6 liters
Step-by-step explanation:
Let x represent the amount of pure concentrate used to make the punch. Then the total amount of concentrate in the punch is ...
0.20·10 +1.00x = 0.50(10+x)
x +2 = 0.5x +5 . . . . . eliminate parentheses
0.5x = 3 . . . . . . . . . . .subtract 2+0.5x
x = 6 . . . . . . . . . . . . . multiply by 2
6 liters of pure concentrate must be added to make a 50% punch.
Hi,
The request actually is to choose functions whose derivative is a constant.
For A, derivative is , which is not constant.
For B, derivative is 2ˣ·ln2, which is not constant.
For C, derivative is 0, which is a constant.
For D, derivative is 1, which is a constant.
So, you can choose C and D.
Have you understood ?
Green eyes.
2x =3 is the first one , first one is B and 2nd one is D I believe
The answer is 40 because if you multiply 4 times per week× for 10 weeks=40 times for ten weeks.
ANSWER
EXPLANATION
The given line passes through (1,4) and (3,-4).
The slope of this line is calculated using the formula:
We substitute the points into the slope formula to get:
We substitute the first point and slope into the point-slope formula
This implies that
We expand to get
